The primary objective of this study is to evaluate a systematic design’s effectivity in remediating actual uranium-contaminated soil. The emphasis was placed on practical and engineering aspects, particularly in assessing the capabilities of a zero liquid discharge system in treating wastewater derived from soil washing. The research method involved a purification procedure for both the uranium-contaminated soil and its accompanying wastewater. Notably, the experimental outcomes demonstrated successful uranium separation from the contaminated soil. The treated soil could be self-disposed of, as its uranium concentration fell below 1.0 Bq·g−1, a level endorsed by the International Atomic Energy Agency for radionuclide clearance. The zero liquid discharge system’s significance lay in its distillation process, which not only facilitated the reuse of water from the separated filtrate but also allowed for the self-disposal of high-purity Na2SO4 within the residues of the distilled filtrate. Through a comparative economic analysis involving direct disposal and the application of a remediation process for uranium-contaminated soil, the comprehensive zero liquid discharge system emerged as a practical and viable choice. The successful demonstration of the design and practicality of the proposed zero liquid discharge system for treating wastewater originating from real uranium-contaminated soil is poised to have a lasting impact.

Spodoptera species (S. exigua and S. litura) are important pests of several crops and vegetables in Korea. We investigated development processes of Spodoptera species under constant temperatures (20, 25 and 30 oC) regimes and relative humidity (RH) (30-35, 50-55, 70-75, and 90-95%) conditions. We collected eggs of Spodoptera species by releasing them into a rectangular box inner walls covered with a sheet of white paper. Temperature and RH significantly impacted on oviposition, immature survival, adult emergence and longevity of Spodoptera species. Maximum number of eggs, shorter developmental time, higher adult emergence with longer longevity were reported in 70-75% at 30 oC. Minimal eggs and larval survival were recorded in 30-35% and 90-95% RH, respectively. This results suggest that temperature and RH had individual apparent effect on the developmental processes of Spodoptera species instead interactive effect. Therefore, there is chance to cause a significant damage to field crops and vegetables in 70-75% at 30 oC.

최근 살진균제는 세계 식량 안보에 없어서는 안될 필수 요소이며, 그 사용량은 증가하고 있다. 살진균제는 직접적 또는 간접적으로 곤충에 영 향을 미쳐 유전자 및 분자 수준의 변화를 일으킨다. 곤충은 다양한 해독 매커니즘을 통해 살진균제를 포함한 농약으로부터 유발되는 활성산소 (ROS) 독성을 제거한다. 본 연구는 살진균제 캡탄의 비치명적 투여량(0.2, 2, and 20 μg/μL)을 주입 후 갈색거저리의 유충에서 해독효소의 mRNA 발현량을 분석했다. 갈색거저리의 전사체 분석을 통해 해독 매커니즘 관련 유전자인 퍼옥시다제(POX), 카탈라제(CAT), 슈퍼옥사이드 디스뮤타제(SOD) 및 글루타티온-S-트랜스퍼라제(GST)를 발굴하였다. 처리 24시간 후 TmPOX5 mRNA가 유의하게 증가한 것으로 나타났다. 처리 3 시간 후 TmSOD4의 mRNA가 유사하게 증가하였다. 또한 2 μg/μL 처리 24시간 후 TmCAT2의 mRNA 가 유의하게 증가하였다. 캡탄 노출 후 TmGST1 및 TmGST3의 mRNA 발현량도 증가하였다. 결론적으로, TmPOX5 및 TmSOD4 유전자는 갈색거저리에서 캡탄 노출에 대한 바이오마커 또는 생체이물 센서로 작용할 수 있음을 시사한다.

The global mushroom industry has grown rapidly in recent years in terms of beneficial effects, market value, and demand. India has a wide range of agro-climatic conditions and is largely an agricultural country with a cultivated area of about 4.37 %, generating about 620 million tons of agro waste annually. Mushroom cultivation not only helps recycle agro wastes, but also fills the nutritional gap prevalent among a large population of India. Recently, government industrial policy and creative innovation has promoted research and other endeavors aiming towards the cultivation of mushrooms. Mushroom cultivation in India was initiated in Solan, in the mid-sixties. Mushroom cultivation has been successful in temperate regions of the Himalayas, the Western Ghats, and the hills of northeast India. Recently, many unemployed people have begun to adopt mushroom cultivation as a means of self-employment. It is high time that Indian mushroom cultivators and consumers became aware of the nutritional and medicinal values of cultivated and wild species of mushrooms. The total mushroom production in India between 2010 and 2017 was approximately 0.13 million tons, accounting for a 4.3% increase in the average growth rate of mushrooms per annum. In particular, the total production of white button mushrooms is the highest, with a share of about 73% of total mushroom production. In this review article, we have analyzed the current scenario of the Indian mushroom industry and its contribution to the economic growth of the country.

Nysius Dallas, 1852, is one of the most common and widely distributed genera under the superfamily Lygaeoidae. Species under this genus are hard to identify due to similarity of the species and variability of the coloration. The Nysius species were collected with the help of aspirator and plastic vile in the perilla crop fields in RDA, Miryang, Korea. Korean species of the Nysius were identified, and three species including a newly reported species N. inconspicuus were recognized. Morphological and genetic characteristics of species were illustrated, and a key to species of Korean Nysius was provided. The DNA barcoding information of N. plebeius and N. inconspicuus were recorded.
